The correct answer is to configure External Identities and add identity providers for social networks. This is because Microsoft Entra ID’s External Identities feature is specifically designed to support social media sign-in by federating with providers like Microsoft, Google, and Facebook using OAuth 2.0 or OpenID Connect protocols, allowing users to authenticate with their existing social accounts without creating separate Entra ID accounts. On the MS-102 exam, this scenario tests your understanding of identity federation versus direct user provisioning—a common trap is confusing External Identities with B2B collaboration guest users, but the key distinction is that social sign-in relies on configuring identity providers under the External Identities blade, not inviting external users manually. For a quick memory tip, think “Social = External Provider” to remember that social media sign-in always requires adding an external identity provider, not just enabling self-service sign-up.

Correct answer & explanation
✓
Configure External Identities and add identity providers for social networks
Option B is correct because Microsoft Entra ID supports External Identities, which allow you to add social identity providers (Microsoft, Google, Facebook) as external authentication sources. This enables users to sign in with their existing social accounts by configuring federation with those providers using OAuth 2.0 or OpenID Connect protocols, without needing to create separate Entra ID accounts.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Configure Conditional Access policies for social identity providers
Why it's wrong here
Conditional Access controls access after authentication, but does not add identity providers.

✗
Configure Microsoft Entra Connect to sync social account attributes
Why it's wrong here
Microsoft Entra Connect syncs on-premises AD, not social identity providers.
✗
Configure self-service password reset (SSPR)
Why it's wrong here
SSPR allows users to reset passwords, not sign in with social accounts.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Conditional Access policies with identity provider configuration, thinking policies can add or manage external authentication sources, when in fact Conditional Access only enforces rules on already-configured providers.
Detailed technical explanation
How to think about this question
When you add a social identity provider in External Identities, Entra ID uses the provider's OAuth 2.0 authorization endpoint and token endpoint to authenticate users. The user is redirected to the social provider's login page, and upon successful authentication, Entra ID receives an ID token (typically a JWT) containing claims like email and name, which are mapped to the user's guest account in the tenant. This allows for seamless B2B collaboration scenarios where external users can access resources without needing a separate Microsoft account.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
